WOVEN PILE FABRIC.

Specification of Letters Patent.

l 'atented Sept. 21, 1909.

Application filed May 23, 1908. Serial No. 434,487.

State of Massachusetts, have invented certain new and useful Improvements in WVoven Pile Fabric, of which the following is a specification.

. My invention relates to woven pile fabr c, and particularly to the class of pile fabrics shown and described in U S. Letters Patent, No. 747,588.

The object of my invention is to improve upon the weave of the fabric shown and described in said patent. In the fabric shown and described in' said patent, there are two filling threads. one for each pile warploop, above the stull'er warp or warps, and two filling threads below the stutter warp or warps, and pile warps, making four filling threads, and two loops of pile warps in each shed, and said fabric is made with two har nesses for the binder warps which harnesses are raised and lowered every four picks.

In my improved pile fabric I use four harnesses for the binder warps, one pair of harnesses for example will change after the first, second, fifth, and sixth pick, while the other pair of harnesses will change after the third, fourth, seventh, and eighth pick, and so on; that is the pairs of harnesses are raised and lowered alternately.

In my improved pile fabric, I hav e an upper and a lov. er filling plane, comprising binder warp threads, and one or more stufier warps, and' one filling thread in the upper lane of the fabric, and one filling thread in the lower plane of the fabric, in each shed formation, and pile warps in the upper plane of the fabric passing about the filling threads in said upper plane. v

I have shown in the drawing, on an enlargedscalc, a longitudinal section of my pile fabric, as a cut pile fabric.

In the accompan mg drawing, 1 are the pile warps, which orm the loops of pile m the upper plane of the fabric, which may be uncut for Brussels carpet fabric, or cut, as shown in the drawings, for .Axminster, or moquette carpet fabrics.

- The pile warp l is bound into the upper plane of the fabric by a filling thread 2, which exlends transversely through the fabric over the pile warp 1, as shown. The stufi'er warps 3, in this instance three in number. extend longitudinally through the fabric in the central portion thereof below the pile warps l, and the upper filling threads 2. The filling threads 4 extend below the stuii'er warps 3.

The binder warps 5 and G for one pair of harnesses, and the binder warps 7 and 8 for the other pair of harnesses, are raised and lowered alternately, to form the shed for the upper filling threads 2, and the lower filling threads at, and the binder warps 5 and G, and T and 8 act to bind the upper filling threads 2, and the lower filling threads 4 firmly on both sides, as shown.

In each shed formed by the harnesses, there is one upper filling thread 2 for one loop of pile warp 1 above the stuffer war 5 3, and one lower filling thread 4 below t e staffer warps 3. There may be one or more stuifer warps 3.

It will be understood that the details of the weave of my improved fabric may be varied if desired, and my weave may be used for an uncut pile fabric, as Brussels carpet, or a cut pile fabric, as an Axminster, or m0- quette carpet.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A single pile fabric having an upper and a lower filling plane, and comprising binder warps, and one or more staffer warps extending in a plane between the upper filling plane and the lower filling plane, and a single filling thread in the upper plane, and a single filling thread in the lower plane of the fabric in each shed formation, and pile warps in the upper plane of the fabric passing about each one of the filling threads in said upper plane, and one-half of the binder warp threads crossed after each insertion of an upper filling thread and a lower filling thread.

2. A single pile fabric having an upper and a lower filling plane, and comprislng 100 binder warp threads, one-half of said binder warps crossed, after each insertion of an upper filling thread, and a lower filling thread, and one filling thread. in the upper plane, and one filling thread in the lower 105 plane of the fabric in each shed formation, and pile warps in the upper fabric passing about each 0 the filling threads of the upper plane, and projecting from one face of the fabric between each of 110 lane of the binder warp threads, one-half of said binder warp threads crossed, after each insertion of an upper filling thread and a lower filling thread, and one filling thread in the upper plane, and one filling thread in the lower plane of the fabric in each shed formed by the binder warps, and pile warps in the upper plane of the fabric passing about each of the filling threads of the upper plane, and bound only by the filling threads'in the upper plane of the fabric, and each filling thread in the fabric bound by the binder warps on both sides of the filling threads 4. A single pile fabric having an upper and a lower filling plane, and comprising binder warp threads, one-half of said binder warp threads crossed, after each insertion of an upper filling thread and a lower filling thread, and one or more stufier warps extending in a plane between the upper filling plane and the lower filling plane, one filling thread in the upper plane of the fabric, and one filling thread in the lower plane of the fabric in each shed formation, and pile warps in the upper plane of the fabric passing about the filling threads in the upper plane.

5. A single pile fabric having an upper and a lower filling plane, and comprising binder warps, and one or more stufi'er wa 5 extending in a plane between the upper fi 1- ing lane and the lower filling plane, and a sing e fillin thread in the upper plane, and a single filhng thread in the lower plane of the fabric in each shed formation, and pile warps in the upper plane of the fabric, passing about each one of the filling threads in said upper plane, and one-half of the binder warp threads crossed after each insertion of an upper filling thread and a lower filling thread.

6. A pile fabric having an upper and a lower filling plane, and comprising binder warps, and one or more stufi'er warps extending in a plane between the upper filling plane and the lower filling plane, and a single filling thread in the upper plane, and a single filling thread in the lower plane of the fabric in each shed formation, and pile warps in the upper plane of the fabric passing about each one of the filling threads in said upper plane, and one-half of the binder warp threads crossed after each insertion of an upper filling thread and a lower filling thread, by a new shed formation every two picks. v
